America's Oldest "Net Zero" House

This 110-year-old Victorian home in Ann Arbor is America's oldest and Michigan's first Net Zero home.

Kelly and Matt Grocoff bought a 110-year-old Victorian home in Ann Arbor, Michigan's Old West Side Historic District, and immediately set out to make it a "net zero" building, or one that generates at least as much energy as it uses, and—by their definition—"creates zero waste and will be a restorative part of our community."

As it turned out, Kelly and Matt's house earned a lot of superlatives:

  • America's oldest Net Zero residential restoration.
  • Michigan's first Net Zero energy home.
  • America's first Net Zero home restoration in a historic district.
  • \n

Here's how they did it.
